Horizontal Multistage Stainless Steel Pump DF Series For Corrosive Liquid
Description
The DF serie Multistage Ring Section Centrifugal Stainless Steel Water Pump is a configured, ring section, multistage pump specifically designed for high pressure feed service in long distance water tranferring applications. Its improved hydraulic performance makes it suitable for any other high pressure application with clean liquids. Its wet parts all made by stainless steel, which makes the pump suitable for corrosive liquid like petrochemic liquid, sea water, hot water, etc.
Features and Benefits
* Greater reliability from radially split pressure casings, ensuring overall pump concentricity and rotor alignment.
* Improved service life and tolerance to changing conditions due to precision-cast diffusers that equalize radial loads and increase bearing, wear ring and seal life.
* Decreased maintenance costs and longer service intervals enabled by heavy-duty rotor with short bearing spans, which minimizes deflection.
* Precise hydraulic configuration made possible by the modular segmental ring diffuser design plus numerous options.
